一、介紹
運用UniApp+Vue+Vuex+swiper+uniPop等技術開發的仿微信原生App聊天室|仿微信聊天界面實例項目uniapp-chatroom,實現了發送圖文消息、表情(gif圖),圖片預覽、地圖位置、長按菜單、紅包/錢包、仿微信朋友圈等功能。
二、測試效果
H5 + 小程式 + App端測試效果如下,實測多端效果均為一致。(後續大圖統一展示App端)
二、技術選型
- 編輯器:HBuilder X
- 技術框架:uni-app + vue
- 狀態管理:Vuex
- iconfont圖標:阿裡字體圖標庫
- 自定義導航欄 + 底部Tabbar
- 彈窗組件:uniPop(基於uni-app封裝模態彈窗)
- 測試環境:H5端 + 小程式 + App端(三端均相容)
- 高德地圖:vue-amap
◆ 頂部導航欄headerBar
頂部導航欄採用的是自定義模式,具體可參看這篇文章:uni-app自定義導航欄按鈕|uniapp仿微信頂部導航條
在pages.json裡面配置globalStyle,將navigationStyle設為custom時,原生頂部導航欄不顯示,這時就能自定義導航欄
"globalStyle": {"navigationStyle": "custom"}
◆ 引入公共樣式/組件及全局彈窗
import Vue from 'vue' import App from './App' // >>>引入css import './assets/fonts/iconfont.css' import './assets/css/reset.css' import './assets/css/layout.css' // >>>引入狀態管理 import store from './store' Vue.prototype.$store = store // >>>引入公共組件 import headerBar from './components/header/header.vue' import tabBar from './components/tabbar/tabbar.vue' import popupWindow from './components/popupWindow.vue' Vue.component('header-bar', headerBar) Vue.component('tab-bar', tabBar) Vue.component('popup-window', popupWindow) // >>>引入uniPop彈窗組件 import uniPop from './components/uniPop/uniPop.vue' Vue.component('uni-pop', uniPop) Vue.config.productionTip = false App.mpType = 'app' const app = new Vue({ ...App }) app.$mount()
◆ Vuex + uniapp登錄驗證
import Vue from 'vue' import Vuex from 'vuex' Vue.use(Vuex) export default new Vuex.Store({ state: { user: uni.getStorageSync('user'), token: uni.getStorageSync('token'), }, mutations: { // 存儲token SET_TOKEN(state, data) { state.token = data uni.setStorageSync('token', data) }, // 存儲用戶名 SET_USER(state, data) { state.user = data uni.setStorageSync('user', data) }, ... }, })
<script> import { mapState, mapMutations } from 'vuex' import util from '../../utils/util.js' export default { data() { return { formObj: {}, } }, computed: { ...mapState(['user', 'token']) }, mounted() { // 判斷是否有登錄 if(this.user){ uni.redirectTo({url: '/pages/index/index'}) } }, methods: { // 提交表單 handleSubmit(e) { ... } } } </script>
◆ 仿微信朋友圈透明導航欄
通過onPageScroll函數實現自定義導航上下滑動自動調整導航欄的透明度,滑動到距離頂部200 效果如下圖二
/** * @tpl 朋友圈模板 */ <template> <view class="flexbox flex_col"> <header-bar :isBack="true" title="朋友圈" :bgColor="{background: headerBarBackground}" transparent> <text slot="back" class="uni_btnIco iconfont icon-arrL"></text> <text slot="iconfont" class="uni_btnIco iconfont icon-publish mr_5" @tap="handlePublish"></text> </header-bar> <view class="uni__scrollview flex1"> <view class="uni-friendZone"> ... </view> </view> </view> </template> <script> export default { data() { return { headerBarBackground: 'transparent' } }, onPageScroll : function(e) { // console.log("滾動距離為:" + e.scrollTop); this.headerBarBackground = 'rgba(65,168,99,'+e.scrollTop / 200+')' }, methods: { ... } } </script> <style scoped> </style>
◆ uniapp實現聊天頁面滾動至底部
在h5端將聊天頁面滾動到底部很好實現,小程式中通過設置scroll-view屬性scroll-into-view的值也能實現,可是在uni-app裡面怎麼將聊天信息滾動至底部呢?
uni-app通過判斷聊天內容高度和scroll-view高度的大小設置滾動距離
<scroll-view id="scrollview" scroll-y="true" :scroll-top="scrollTop" style="height: 100%;">
<view class="uni-chatMsgCnt" id="msglistview">
<view class="msgitem">xxx</view>
<view class="msgitem">xxx</view>
<view class="msgitem">xxx</view>
...
</view>
</scroll-view>
export default { data() { return { scrollTop: 0, ... } }, mounted() { this.scrollToBottom() }, updated() { this.scrollToBottom() }, methods: { // 滾動至聊天底部 scrollToBottom(t) { let that = this let query = uni.createSelectorQuery() query.select('#scrollview').boundingClientRect() query.select('#msglistview').boundingClientRect() query.exec((res) => { // console.log(res) if(res[1].height > res[0].height){ that.scrollTop = res[1].height - res[0].height } }) }, ... } }
◆ uniapp聊天代碼片段
<script> const emotionJson = require('./mock-emotion.js') const messageJson = require('./mock-chat.js') export default { data() { return { scrollTop: 0, showFootToolbar: false, showEmotionChoose: false, editorText: '', editorLastCursor: null, // 表情json emotionList: emotionJson, // 消息記錄 messageList: messageJson, // 預覽圖片臨時數組 previewImgArray: [], } }, mounted() { this.scrollToBottom() }, updated() { this.scrollToBottom() }, methods: { // 滾動至聊天底部 scrollToBottom(t) { let that = this let query = uni.createSelectorQuery() query.select('#scrollview').boundingClientRect() query.select('#msglistview').boundingClientRect() query.exec((res) => { // console.log(res) if(res[1].height > res[0].height){ that.scrollTop = res[1].height - res[0].height } }) }, // 點擊聊天消息區域 msgPanelTaped() { if(!this.showFootToolbar) return this.showFootToolbar = false }, // 表情、選擇區切換 swtEmotionChooseView(bool) { this.showFootToolbar = true this.showEmotionChoose = bool }, ... // 點擊表情 handleEmotionTaped(emoj) { if(emoj == 'del') return // 在游標處插入表情 let startStr = this.editorText.substr(0, this.editorLastCursor) let endStr = this.editorText.substr(this.editorLastCursor) this.editorText = startStr + `${emoj}` + endStr }, // >>> 【選擇區功能模塊】------------------------------------------ // 選擇圖片 handleLaunchImage() { let that = this let msglist = this.messageList let len = msglist.length // 消息隊列 let data = { id: `msg${++len}`, msgtype: 5, isme: true, avator: '/static/uimg/u__chat_img1.jpg', author: 'King', msg: '', imgsrc: '', videosrc: '' } uni.chooseImage({ count: 1, sourceType: ['album'], success: function(res){ // console.log(res) // console.log(res.tempFilePaths) data.imgsrc = res.tempFilePaths.toString() msglist = msglist.concat(data) that.messageList = msglist } }) }, ... // 位置 handleChooseLocation() { let that = this let msglist = this.messageList let len = msglist.length // 消息隊列 let data = { id: `msg${++len}`, msgtype: 8, isme: true, avator: '/static/uimg/u__chat_img1.jpg', author: 'King', msg: '', imgsrc: '', videosrc: '' } uni.chooseLocation({ success: (res) => { console.log(res) // 插入消息 data.msg = { name: res.name, address: res.address, latitude: res.latitude, longitude: res.longitude } msglist = msglist.concat(data) that.messageList = msglist } }) }, } } </script>
